Abstract (en)
[origin: EP2618470A2] The DC-DC converter has transformer (11) having primary winding (L1) connected to input unit via switching element (T1), and secondary winding (L2) having output circuits to provide output voltages to processing channels. A pulse width modulator (12) controls switching element in pulsed manner. A controller (14) associated with first output circuit controls modulator so that output voltage of first output circuit is stabilized. An output-side voltage regulator (15) is associated with second output circuit so that output voltage of second output circuit is stabilized.
